AASHTO Guide for High Occupancy Vehicle HOV Facilities

Guide for High-Occupancy Vehicle (HOV) Facilities, 3rd Edition This guide suggests methods and designs for dedicated facilities to encourage greater use of existing transportation systems, such as increased use of public transit (primarily buses), carpools, vanpools, or other ridesharing modes.

AASHTO Guide for High Occupancy Vehicle HOV Facilities Guidance is given for planning and design of preferential treatment for high-occupancy vehicles (HOVs). Portions of this guide have been excerpted from the previous edition of this guide which this guide replaces, the National Cooperative Highway Research Program (NCHRP) HOV Systems Manual, and recent research from Texas

OVERVIEW OF GUIDE AASHTO Guide for High Occupancy Vehicle HOV Facilities
This guide is intended asjust that a guide. Where this guide does not provide speciﬁc geometric information, please refer to A Policyon Geometric Design of Highways and Streets forguidance. In some chapters, this guide provides desirable and minimum crosssections and design criteria. Prior to implementing designs that are less than the minimums,an engineering review should be completed with respect to the safety and operational impacts of these geometric elements and their justiﬁcation.

For minimum designs, the designer should review Section 2.1, which describes the link between design, operations,and enforcement of HOV facilities to better understand the conditions underwhich the minimum designs might be appropriate and what operational treatments might be necessary.

The Federal Highway Administration FHWA, Federal Transit Administration FTA, state Department of Transportation DOT, transitagency, city, and others should agree on the most appropriate cross-section and other geometric design elements.

A formal design exception request may need to be processed to document the decisions and their approvals. The guide also has a glossary to acquaint the reader with certain expressions and terminology that are used in this guide. The ﬁve chapters in the guide are described below.
